Led by Dr. Qaria, biomedical scientist with two PhDs (https://optelux.com/author/dr-qaria/).
- [How to Read Your Eyeglass Prescription](https://optelux.com/how-to-read-eyeglass-prescription/): OD is your right eye and OS your left; some prescriptions write RE and LE. SPH is the main lens power: minus means short-sighted, plus means long-sighted. CYL and AXIS together correct astigmatism and are blank if you do not have it. ADD is extra power for reading. PD is often missing and is measured separately.
- [AR Virtual Try-On Glasses vs AI Face Measurement](https://optelux.com/ar-ai-applications-in-online-eyewear-stores/): Virtual try-on answers whether a frame suits you: shape, colour and rough proportion. It cannot judge bridge contact, temple pressure, weight or exact scale. Face measurement answers whether it fits, giving you a PD and face widths to compare with a frame's published dimensions in millimetres. Use try-on to narrow the field, then measurement to check fit.
- [Frame Colour and Finish: A Professional Guide](https://optelux.com/luxury-eyewear-for-professionals-frames-colors-ai-fit/): Choose frame colour by three things: your skin undertone, the light you work in, and how often you are on camera. Warm undertones suit gold, bronze and warm brown; cool undertones suit silver, gunmetal and matte black; neutral suits almost anything. Matte and brushed finishes work better on video calls than polished ones, which throw bright highlights.
- [Best Aviator Sunglasses for Men: A Buyer's Guide](https://optelux.com/top-aviator-sunglasses/): The best aviator sunglasses for men combine polarised lenses, which cut reflected glare from roads and water, with UV400, which blocks UV up to 400 nanometres. Choose a light metal frame that ends near the widest point of your face. The classic teardrop suits oval, oblong and square faces; the straighter square pilot suits round and oval faces.
- [How Much Do Titanium Glasses Weigh? We Put Five on a Scale](https://optelux.com/how-much-do-titanium-glasses-weigh/): We weighed OpteLux titanium frames on a jeweller's scale: the ONC8803 was the lightest at 7.83 g and the OSZCN054 the heaviest at 13.77 g, frame only. Prescription lenses add more, depending on your prescription, lens material and index.
- [Titanium Eyeglass Frames: Why Professionals Are Switching](https://optelux.com/titanium-eyeglass-frames-why-professionals-are-switching/): Professionals who wear glasses for long days choose titanium because it is light, strong for its weight and flexible. Commercially pure titanium contains no nickel and does not corrode with sweat or humidity, so frames keep their shape and finish. Check that a frame is pure titanium rather than a titanium alloy, and compare its published weight and dimensions.
- [Titanium vs Acetate vs Stainless Steel Glasses Frames](https://optelux.com/titanium-vs-acetate-vs-stainless-steel-frames/): Titanium is the lightest of the three, does not corrode and contains no nickel in its commercially pure form, so it suits all-day wear and reactive skin. Acetate gives colour, layering and translucency that metal cannot. Stainless steel is the durable, lower-cost middle ground, with nickel as its main caveat. Choose by hours worn, skin history and handling, then style.
- [How to Measure Your PD (Pupillary Distance) at Home](https://optelux.com/how-to-measure-pd-at-home/): Your PD is the distance in millimetres between the centres of your pupils. To measure it at home, stand about 20 cm from a mirror, hold a millimetre ruler flat against your brow, line zero up with the centre of your right pupil, and read the mark over your left pupil. Repeat two or three times and take the average.
- [Best Glasses Frames for Men in 2026: How to Choose](https://optelux.com/best-glasses-frames-for-men-in-2026-how-to-choose-like-a-professional/): Start with shape, using contrast: angular frames suit round faces, round or oval frames soften square faces, and oval faces suit most shapes. Then check material and fit. Titanium is light and holds its shape through daily wear. The frame should end near the widest point of your face, with a bridge and temple length that match a pair you know fits.
- [How to Buy Glasses Online: The Complete Guide for Men](https://optelux.com/how-to-buy-glasses-online-the-complete-guide-for-men/): Buying glasses online is straightforward if you do three things first. Read your prescription: SPH, CYL, AXIS and ADD. Get your PD, from your optician or a measurement tool. Then compare each frame's lens width, bridge and temple length with a pair that already fits you. Skipping those steps is where online orders usually go wrong.
- [The OpteLux Design Philosophy: Eyewear as Equipment](https://optelux.com/behind-the-frames-the-optelux-design-philosophy/): OpteLux designs eyewear as equipment for long working days rather than as a style purchase. Most OpteLux eyeglass frames are 100% Grade-A titanium, so they are light, hypoallergenic and resist corrosion. Frame dimensions are published in millimetres, fit is checked with free face and PD measurement, and lenses are designed in Japan and France and made in Asia and France.
- [How Eyewear Reads in Professional Settings](https://optelux.com/why-is-executive-titanium-eyewear-the-new-power-move/): At work, glasses are judged by proportion and finish more than by brand. A frame that matches the width of your face and sits level reads as deliberate; one that is too wide, heavy or crooked reads as careless. Thin metal profiles read as understated and senior, bold acetate as creative. On video calls, the frame takes up more of the picture.
- [How to Clean and Care for Your Glasses Properly](https://optelux.com/premium-eyewear-care/): Rinse your glasses under lukewarm running water before you wipe them, so grit floats off instead of scratching the coating. Use a drop of lens cleaner or a mild, additive-free washing-up liquid, rinse again, and dry with a clean microfibre cloth. Store them in a case, take them off with both hands, and keep them away from heat.
- [Best Glasses for Working on a Computer All Day](https://optelux.com/best-glasses-for-working-at-a-computer-all-day/): Screens sit at an intermediate distance of about 50 to 70 cm, between distance and reading prescriptions. The best lens for PC work is a single vision intermediate lens, or an office progressive if you are over 40. Add an anti-reflective coating, choose a light titanium frame, and make sure the lenses are centred on an accurate PD.
- [Do Blue Light Glasses Work? Blue Light vs Normal Glasses](https://optelux.com/do-blue-light-glasses-actually-work-what-professionals-need-to-know-in-2026/): A blue-light filter filters part of the blue light from screens. On its own it is not the deciding factor. How comfortable a pair is through a long screen day depends more on the whole pair: lens quality, an anti-reflective coating, a light, well-fitted frame, and optical centres that match your PD. A cheap filter in a poor frame does not fix fit.
- [Lens Index Explained: 1.50 to 1.74, Which Do You Need?](https://optelux.com/lens-index-explained/): Lens index measures how strongly a lens material bends light. A higher index lets the same prescription be made thinner and lighter, but it does not make you see more sharply. Add your SPH and CYL together and choose for that figure. Most people only need more than a standard 1.50 to 1.52 lens once that figure passes about 2.00.
- [How to Choose Eyeglasses for Your Face Shape](https://optelux.com/eyeglasses-for-your-face-shape/): Use contrast. Choose frames whose shape is the opposite of your face: angular, rectangular frames for a round face, round or oval frames for a square face, and almost any style for an oval face. Then match scale: the frame should be about as wide as the widest part of your face, with the top of the frame near your brow line.
- [Glasses for Astigmatism: Lenses and Frame Design](https://optelux.com/glasses-for-astigmatism/): Glasses for astigmatism are ordinary prescription glasses with two extra values, CYL and AXIS. Any single vision, reading or progressive lens can carry them. The frame matters more than usual: the correction only works at the angle measured, so choose a frame that sits level, has adjustable nose pads, holds its adjustment and has a moderate lens size.
- [Clip-On vs Prescription Sunglasses: Which Should You Buy?](https://optelux.com/clip-on-vs-prescription-sunglasses/): If you wear glasses every day, clip-on sunglasses are the cheaper, lower-risk buy: they work with the frame you own and can be returned. Prescription sunglasses are better if you drive a lot or spend long hours outdoors, because you get one lens with no join or extra layer. Photochromic lenses work well on foot but darken poorly inside a car.
- [Polarised vs Non-Polarised Sunglasses: Which Should You Buy?](https://optelux.com/polarised-vs-non-polarised-sunglasses/): Polarised sunglasses are the better buy for driving, water and bright days around reflective surfaces, because they cut reflected glare. Non-polarised lenses suit pilots, anyone reading LCD screens outdoors all day, and skiers who need to see ice. Both can block 100% of UV. Polarisation only decides what happens to glare, so check for UV400 separately.
- [Glasses for Work: How to Choose a Pair for a Long Day](https://optelux.com/glasses-for-work/): Good glasses for work are light, fit your PD and match the distance you work at. Choose a light titanium frame whose PD range includes yours, a lens made for your screen distance, an index that suits your prescription strength, and a hardened, easy-clean coating. A spare or a second pair for outdoors makes a long day easier.
- [Design Your Own Glasses Online: Step by Step](https://optelux.com/design-your-own-glasses-online/): To design your own glasses online, start from your PD, then choose a frame whose PD range fits it, a frame colour, your lens use and thickness, a coating and any extras. Add personal touches such as name engraving if you like. Check your PD, sight test, lens choice and the return policy before you order.
- [Rimless, Half-Rim or Full-Rim Glasses: Which Should You Buy?](https://optelux.com/rimless-vs-half-rim-vs-full-rim-glasses/): A full rim hides the lens edge and takes any lens, so it suits strong prescriptions and bold looks. A half rim gives a brow line with an open lower half. A rimless frame almost disappears but needs drilled lenses, usually one index band up, and careful handling. Weight depends more on the frame material and the lenses than on the rim style.
- [Glasses Size Explained: What 52-18-145 Means](https://optelux.com/glasses-size-explained/): The three numbers inside a glasses arm are lens width, bridge width and temple length in millimetres, so 52-18-145 means a 52 mm lens, an 18 mm bridge and 145 mm arms. Lens plus bridge gives the frame PD. Start from a pair that fits, keep frames whose PD range includes yours, and get the bridge right first.
- [Are Titanium Glasses Worth It? Cost, Comfort, Downsides](https://optelux.com/are-titanium-glasses-worth-it/): Titanium glasses are worth it if you wear glasses most of the day. You get low weight, flexibility and corrosion resistance. You accept a higher price, harder repairs and fewer bold looks. For a spare pair or occasional reading glasses, a basic frame is usually enough, and fit always matters more than material.
